Another suggestion, go back a few years and read Susie Orbach's (I think its spelt correctly?) book, 'Dieting makes you fat'.
I've never dieted myself, although at times I eat less food, it all depends on my mood. Is this dieting? Never really sure what 'to diet' actually means?
My GP, who's retired now, always told us that the most dangerous stuff, in his opinion, is salt and sugar. My wife and I havn't bought such items, except on odd occasions when we have had work done in and/or on our house, just to keep the staff happy, or when visitors come and obviously can't live without it. Why do so many tradesmen have one to three teaspoons of sugar in their coffee or tea? I suppose its the same as asking why do so many off them read the Sun as well? When they have finished their work and have gone we just flush the rest away. Likewise, fish and chips, we never have salt on them, only vinegar.
Sorry but I only ramble on like this because to achieve a 'genuine and lasting' weight loss, I suspect it is much more comlicated than capitalism wants us to believe. Obviously for them its a cash cow! The observation I made years ago and I'm still of the same opinion now, is that there is a vast world wide industry out there, enticing people to spend and diet in all sorts of ways. They were there when I was young and they are still there selling their ideas (nonsense?) but interstingly people are still fat! My conclusion as a simple member of the public, is that dieting does NOT work! It may appear to work, peoples do notice when their weight drops, but as soon as they realx, there weight goes up because most people I think just go back to their old life and eating routine.
I get emailed hassled by something call Jane Plan, I've no idea who they are or what their selling, but the emails come to me most day. I just delete them.
